reassign -1 libqt5webenginecore5 5.14.2+dfsg1-5 thanks Hey,
Since you can reproduce this with Falkon, it definitely isn't an issue
in qutebrowser. Reassigning this to QtWebEngine. Let's hope it works,
I'm not too experienced with using Debian's BTS - whoever is on the
receiving end, please let me know if I messed up something :)

Thanks! For reference, here's a demangled version of the relevant stack

From a quick search in QtWebEngine's and Chromium's bugtracker I
couldn't find anything relevant... I also don't remember seeing this
stacktrace before.
As a workaround, you might want to try the different settings for
"qt.force_software_rendering" in qutebrowser and see if they change
anything. Note they require a restart after being set.

No clue on that one, but it's most likely unrelated to the crash FWIW.

Those are unrelated, though they should be fixed in Falkon I guess.
I'm not sure if it's still maintained really...
